"The Cayman Trough may be a 'lost world' that will give us the missing piece in a global puzzle of deep-sea life," says Dr Copley, a lecturer with the University of Southampton’s School of Ocean and Earth Science. Volcanic vents in the Atlantic are home to swarms of blind shrimp and beds of unusual mussels. But similar deep-sea vents in the eastern Pacific are inhabited by bizarre metre-long tubeworms. The researchers hope to find out whether creatures living in the Cayman Trough are related to those in the Pacific or the Atlantic – or completely different to both.
